LAMP-EXTINGUISHING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 380,129, dated March 2'7, 1888. Application filed April 7, 1887. Serial No. 234,012. (No model.)

To all whom it may concern/ Be it known that we, JOSEPH MILLER and FRANK R. PAGE, of Clean, in the county of Cattaraugus and State of New York, have invented a new and Improved Lamp-Extinguishing Attachment, of which the following is a full, clear, and exact description.

Our invention relates to an improvement for automatically extinguishing lamps, and has for its object to provide a simple and reliable device capable of attachment to any lamp, but especially adapted for railroad-car lamps, wherein, in the event of a collision or accidental upsetting of a car, the lamps will be simultaneously extinguished.

The invention consists in the construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure 1 is a front elevation of the device, partly in section, applied to a lamp; and Fig. 2 is a plan view thereof.

A case, 1, is attached to the wall or other vertical support at one side thelamp 2, preferably in substantial alignment with the burner; or the casing may be secured to the lamp-body itself. The casing 1, which may be ornamental or otherwise, is provided at the base, about centrally the same,with an aperture, 3, and at the top with a smaller aperture, 4, the center of the two apertures being preferably in the same vertical plane.

Abar or cross-head,5,provided with angular projections or pivotal pins 6, integral with its under face at the ends, is supported by said pivot-pins inside the casing upon the bottom thereof transversely the lower aperture, 3, as shown in Fig. 1. Centrally the under side of the cross-head 5 a rod or stem, 7, is attached, adapted toproject downward below the casing, to which stem 7 ,near the bottom, a weight, 8, is adjustably secured by a set-screw, 9, or equivalent means.

In the center of the cross-head 5, uponthe upper face, a V'shaped groove, 10, is cut,

cal rod, 11, which rod, extending through the aperture 4, is pivotally attached to the short end of astraight or curved lever,12, fulcrumed upon the casing at 19.

adapted to receive the angular end of a verti- The lever 12 is-pivotally united with a sec- 0nd lever, 13, fulcrumed'upon the lamp-casing at 18 by a connecting-bar, 14, one end of the said second lever, 13,being adapted to project within the lamp,where it is pivotally con- I nected, through the medium of the short bar 15, with a sleeve, 16, encircling and adapted to slide upon the wick-tube 17. In operation, when the car is moving ordinarily, the cross-head 5 remains perfectly still upon its pivot 6; but in the event of asudden stoppage of the car when running in either direction the cross-head will be raised by the momentum of the weight 8 at either pivot, according as to the direction in which the carismoving at the time, whereby therod 11 is also elevated, being retained in position by the groove 10, which movement operates the lever 12, and the said lever 12, communicating motion to the lever 13, causes the same to elevate the sleeve 16 above and over the blaze,instantly extinguishing the same.

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1. A device for extinguishing lamps, the

same consisting of an aperturedcasing,a crosshead mounted upon pivots within said casing, having a pendent stem and a weight adjustably secured upon said stem, a vertical rod extending above the casing at one end and bear- 8 5 ing upon the cross-head at the other intermediately of its said pivots, and a lever-connection between said vertical rod and a sleeve adapted to slide over a wick-tube, substantially as shown and described.

2. In a device for extinguishing lamps, the combination, with a casing and a "sleeve, the latter adapted to slide over a wick-tube, of the cross-head provided with pendent pivots near its outer edges and arranged within said 9 casing, a central weighted pendant, the vertical rod having a pointed lower end bearing in .a groove arranged intermediately of said pivots of the cross-head, and thelever-connection between said vertical rod and wick-tube sleeve, substantially as and for the purpose set forth.

3. The combination, with a lamp and the 5 wick-tube thereof, of the casing 1, the crosshead 5, provided with pendent pivots near its outer edges, and having an attached pendant, weighted stem 7, a vertical bar, 11, pivoted in said cross-head intermediately of 10 said pivots, a sleeve, 16, adapted to slide upon the wick-tube, and a pivotal connection between said bar and sleeve, substantially as shown and described.

4. The combination, with a lamp and the wick-tube thereof, of the casing 1, having ap- 15 ertures 3 and 4, and the cross-head 5, provided with pivot-rests 6, an upper central groove, 10, and an integral pendent stem, 7, carrying an adjustable weight, 8,a vertical bar, 11, pivoted in said groove 10 intermediately of said 20 pivot-rests, and a leverconnection between said bar and sleeve, substantially as shown and described.
